With outstanding technical support, delivery reliability and turnaround times, we will not only assist you in choosing the right coating for your requirements but also deliver a high quality service that meets your timescales.

If plasma coating isn’t the best solution, we also have HVOF, Flame Spray, Wire Arc, and Thermal Spray Aluminium services. Click on the following link to read more about our Thermal Spray Coating services.


Key Properties of plasma coatings

Typical Applications

  • Corrosion protection
  • Wear resistance
  • Clearance control – abrasives and abradables
  • Heat and oxidation resistance
  • Temperature management
  • Electrical resistivity and conductivity
  • Turbine blades
  • Gas turbine engine components
  • Down hole tools in oil & gas industry
  • Mining equipment
  • Pump components

How does the plasma spray process work?

The Plasma spray process is known as a ‘cold’ process as the substrate temperature can be kept low throughout (<150°C), and the coating thickness can be accurately controlled. The Plasma flame (argon, nitrogen, hydrogen and helium) melts the powder and propels the molten metal out of the spray gun and onto the substrate. The metal then cools and solidifies forming a very strong bond onto the substrate.

Plasma spray processes

  • Ceramic coatings: e.g. Chrome Oxide, Aluminium Oxide, Zirconium Oxide
  • Abradable coatings: e.g. Nickel Graphite, Nickel Aluminium or Nickel Chrome
  • Pure Metals and Alloys: e.g. Aluminium, Copper Molybdenum, Nickel
  • Carbides: e.g Tungsten Carbide, Chrome Carbide
